How do you implement the app state transitions?

[lexum0]

The app logs in Android the state transitions with onPause, onResume, onStop, onRestart.

How do you override or implement this methods in your app to perform custom logic?

The situation is not ideal, but our generated Android/app/src/main/kotlin/Main.kt file contains onPause, onResume, onStop, onRestart, etc. implementations that you can add logic to. You can call into your app's top-level code from there, and then try to share the logic with whatever you do in the SwiftUI app lifecycle delegates.

Awesome. I thought that file was generated and overwritten on each build.

What do you mean with your app's top level code? What can you call from there? or what options do you have?

Thanks!

No, just once when the app is initialized.

You have access to all the types in the app module (e.g., RootView, ContentView). So you could do something like:

override fun onPause() {
    RootView.staticAppOnPauseFunction() // and then so something with a shared singleton…
    super.onPause()
}

Perfect. Thank you so much!
